This simplifies the renderer handling - the FontRequest arriving there
will always be resolved.
And this reduces the amount of property dependencies: If a Text elements
specifies a font-family, no dependency to the window's
default-font-family is created.
Every backend will do something different with the string that needs to go into the clipboard.
Qt will convert it to a QString, copypasta to a String, in theory it could be written
directly to a socket.
Given that we don't know what the perfect representation on the backend side is, passing
a string slice avoids any immediate conversions.
I want to track component structure changes in the window without
generating more code. So use a more generic name for the init_*_items
functions, so that I can add the functionality I need in there.
Also add a register_component to PlatformWindow and call that.
I want a more generic name as I want to do to track component structure
changes in addition to resource freeing and I do not want to add another
call into the generated code.
Implement basic accessibility (a11y) support, using the Qt backend.
_This should get us started, but accessibility support is an additional way to interact with UIs that is very different from the "graphical way" most users will interact with the UI. No single PR will "make a toolkit accessibility", this needs to be an ongoing effort!_
Parts of this PR:
* Add functions to access a11y-related properties to Component
* Add helper functions to Item struct
* Handle accessible- properties in the compiler
* Add documentation, add description, enforce some basic rules
* Make the Text element accessible by default
* Don't optimize away accessibility property in the LLR
* Ensure that accessibility property are marked as used
* Add some accessibility properties to the native style widgets
* Support for bool and integer `accessible` properties
* Implement basic support for accessibility
* Make basic widgets accessible by default
* Make slider focus-able and interactable with keyboard
* Tell a11y layer about value changes
* Generate QAccessible constants using bindgen
* Don't expose the `accessible` properties when using the MCU backend: There is no backend to make use of them
* Handle focus change based on keyboard focus of the window
* Report accessible widgets at correct positions
* Allow for (virtual) focus delegation at the a11y level
* Calculate value step size dynamically
* Make sure to not send notifications to a11y backend about dead objects
Changing the constraint doesn't work on non-rezsizable window.
So first set the window as resizeable, then change the constraints, then
maybe remove the resizable flag
Do not send keyboard events to invisible widgets, reset the keyboard
focus instead.
That fixes#798 again with a bit less of a work-around. To properly fix
this we will need to make the tab widget (and probably others) more
intelligent though.
This avoid repeating the enums both in the compiler and in
the runtime library, and register them in a bunch of other places.
So it should be easier to add enums and enum values
Since cbindgen doesn't see through the macro, generate the enum
manually
When closing a popup, notify the platform window, so that the mcu
backend can remember that region and start the dirty region with it.
Also, free all the rendering cache items of deleted items, to avoid accidental re-use
when re-opening a popup.

Handle Input event from the input directly instead of going through winit
for the TextInput.
Note that this doesn't handle the composition event well, so the text is
only considered written when it is accepted
